摘要

The Invention relates to a method to enhance the performance of Gold leaching by cyanidation In Treatment of Refractory ores or concentrates of such MineThe Air Delivery, while in an Alkaline Environment at Atmospheric Pressure, in which the Gold present in such ores or concentrates is fixed as teleruros.The method is characterized by making the cyanide to a temperature above the Ambient temperature.Until a value immediately below the Boiling Point of liquid leaching. The treatment is performed appropriately at a temperature of 60 to 80 degrees C.And a pH value between 10 and 12.
